This invention relates to a curtain roll cutter, and more particularlyto improved means for cutting such a roll so as toflt the previouslymeasured window casing.

One feature of this invention is that it provides means for accuratelydetermining the point'at which said roll is to be cut; another featurevof this invention is that it provides guide means at said point for asaw or other cutting tool; vstill another feature of this invention isthat it pro'- vides positive means for holding the curtain roll withoutdanger of slippage or change of position A when it is being cut; yetanother feature of this invention is that it is adapted to receive allcommercial sizes and diameters of 'curtain rolls; another feature isthat two scales are provided, one for inside brackets and :the other foroutside brackets; a still further feature of thisinvention is that thedevice may be set directly at the measured width of the window casing,allowance being automatically made for the tips of each end of the rolland the necessary slack or play; other features and advantages of thisinvention will vbe apparent from the following specification and thedrawing, in whichto brackets mounted on such casings, therefore,

it is necessary to measure the distance between each casing and to cutthe curtain roll and curtain to t that particular window. It has longbeen customary in the trade to measure the casing width, make allowancesfor the tips and the necessary slack, mark a curtain roll by hand with ayardstick or tape, and then saw it by hand. Many errors occurred in thismode of operation, and it is not at all infrequent for 30% of thecurtain rolls cut in this way to iit improperly. Sometimes they may beused even though they have too much or too little slack, but frequentlythey are so far oif as not to fit at all.

corresponding toy the width of the window. It has mounted at one end ofthe scale a supporting block for the curtain roll, with a guide slot'fora saw or the like at the point vat which the curtain roll is to be'cut,determined by placing one end. 5

of it against the block previously set to Ycorrespond to the windowwidth. :The device is so arranged thatv necessaryY allowances for thetipsA and vfor slack is automatically made for both'V inside and n noutside brackets. a Y

In the particular embodimentof this invention illustrated herewith, an`elongated base I0 of wood'orsirnilar material is here shown as of'rectangular shape. 'Ihe base has atone end thereof a supporting block II having therein a supporting 15 slot `I2 adapted to have a curtain rollAlie therein and' be longitudinally slidable therethrough when Y saidrollfis parallelto the long'axis of the basel Theblock I I has a secondor guide slot I3 therethrough `'atfright angles to the slot I2. YThisslot 20 is so constructed and arranged to'actas-aguide for a saw forcutting the roll, or other instrument for marking it. k

The base has slidably mounted thereon a block I 4, which'block is hereshown as mounted by a 25 bolt I5 projecting through a centrallongitudinal slot I6 in the base, provided at the upper end thereofabove the block I4 with a wing nut Il for manually locking the block atany desired point on the base. The block is also here shown with a.spring I 8 for frictionally retaining it. Y

while the wing nut is being tightened. It is to be understood, ofcourse, that this spring is optional and that'any convenient slidablemounting and locking means may be employed. enable the block to slidereadily along the base Without the head of the bolt I5 striking a tableI.

or other place on which the base may be laid, blocks. I9 and 2l) areprovided at the ends of the base to elevate it slightly above thesurface on 40 which it rests.

The base has graduated thereon the two scales 2| and 22, in linearunits'here shown as inches. While these scales are both graduated in thesame units, it will be noted that they are not in registry with eachother, nor do their zero points coin-V cide exactly with the guide slotI3. The scale 2|, intended for use where inside brackets are tobemounted on the window casing haa if.: am

In order to 35 porting slot I2 in the block II is 1%," in widththroughout a part o-r portion of. the length, but

has a reduced lower portion 23 one inch in width. The wider portion ofthe slot thus receives 1% rolls, while the reduced portion will receiveand support inch or rolls. The block I4 has mounted on the face thereof,directed toward the block I l, brackets 24 and 25. Both ofthesebracketsare located in a position which corresponds to the center of thesupporting slot I2, but they are vertically displaced, the bracket 24being at such a height as to coincide withv the center of a. rollsupported inthe wider portion of the slot I2; while the bracket 25,being somewhat lower, coincides with the center of a smaller roll lyinginthe reduced portion 23. Y

Where it is desired to use thisl device to cut a curtain roll to t apreviously measured window casing, it is first determined Whether insideor outside brackets are to be used. vThe bracket edge of the block I4 isthen set at a measured distance on the scale corresponding to thebrackets to be used, and locked in place by tightening the wing nutI'I.v Avcurtainroll o ithe desired diameter then vhas a tip placed onone end thereof, and the curtain roll locked in the slot I2 with the tipmounted in the bracket 24 or 25, depend-- ing upon the diameter of theroll. A saw isthen inserted in the slot I3 and the roll cut,thus'providing an accurately located squarely cut edge.v A cap and tipare then placed on this end of the roll, and it is ready to be mountedon the window casing for which it was intended.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as permissible, in view of the priorart. .i `What I claim as new and desire to secure by Letters Patent is:Y 1. A device-'ofthe character described for determining a point 'atwhich a curtain roll is to be cut, including: an elongated base havingtwo .linear scales rgraduated thereon in the same units but aboute outof registry with each other; a block on one end of said base having asupporting'slot'therethrough parallel to said scales and a guideslottherethrough perpendicular to said scales, said guide slot being locatedbetween the zero points of said'scales, the distance bef tween the zeropointsy and said guide slot Vbeing adapted to compensate for inside andoutside curtain roll brackets; a second block slidably mounted on saidbase adjacent said scales and adaptedv to be set at a predetermineddesired graduation on either of said scales; means for locking saidblock at the point at which it is set; and means on said slidable blockfor supporting one end of said roll when said roll lies in saidsupportingslot. Y l g 2. Apparatus of the character claimed in claim 1,wherein said supporting slot has a portion fof reduced width near thebottom thereof, and said slidable block hastwo supporting kmeans thereoneach of'saidV supporting meansrbeing vadapted to engage the tip mountedon a. curtain roll;
